Princess Eugenie wore the Greville Emerald Kokoshnik Tiara on her wedding day, which was loaned to her by her grandmother, Queen Elizabeth II. The tiara has a rich history dating back over a century, belonging to Margaret Greville, a Scottish servant’s daughter who rose to prominence in Edwardian society. Margaret Greville accumulated a vast collection of jewels, including emeralds and diamonds, and her tiara features a 93.70-carat central emerald. The tiara was later passed down to Queen Elizabeth, the Queen Mother, and was most recently worn by Queen Camilla at the Diplomatic Corps reception in 2025.
